I think Sears or somebody has a two pair for the price of one on this week, may I suggest you visit their optometrist.
I have a 55 inch TV I am using for a computer monitor, just visit a few YouTube links and set the resolution as you like, if you don't see the difference then you are functionally blind and should not drive a car. :)
LMBO!!! And you think I'm blind?
During my vacation this week I got by with a little iPod Touch for my internet. (Okay - I did do that 'spread-out-two-fingers-to-make-the-letters-bigger' thing, but hey.. )
